How can i grab position of mouse in my application, and how can hide or show mouse.
QCursor
Note that Qt::CursorShape enum includes Qt::BlankCursor value.
you can reimplement QWidget's mouseMoveEvent(QMouseEvent *event) and get the current position of the mouse.Quote:

You can use QWidget::setCursor() to change the shape of your cursor.Quote:

This shows the various shapes that you can change your cursor to.
Use BlankCursor to hide and ArrowCursor to show.
Or simply use QCursor::pos(), if you want to know only the current mouse position.Quote:

for limiting the mouse in a window -
1) Convert mouse position from global to window position (use mapFromGlobal())
2) check if that position lies within the window geometry ( Qwidget->geometry())
using these u can limit the movement :)
hope this helps
Do you mean you want to show mouse cursor only in the main window and hide it in all other windows ?Quote:

yes. Only till my application runs.Quote:

hmmm, I think there should definitely be a better way to achieve this, but cannot think of any right now.
Is there a way to get the local coords when using GraphicsView? like perhaps scene coords relative to current view?
QWidget, QGraphicsView and QGraphicsItem all have lots of mapFrom() and mapTo() methods.Quote:
